I like Louis Koo not only because he is a low-key actor, but also because he has been engaged in public welfare for more than ten years. Many netizens quipped: Only the sun can black Louis Koo. We can also see that Louis Koo's skin is really getting darker and darker. It is understood that he will paint himself black just to save time in makeup. In fact, Louis Koo was a small piece of fresh meat when he was young. Did you see his charming eyes?
